Five of our Ryevitalise projects are directly focused on supporting a number of vulnerable species, including the rare alcathoe bat, as well as ancient and veteran trees.
Discover what we're doing with the support of farmers, landowners, land managers and a dedicated team of volunteers and citizen scientists.
1) Bat Acoustic Monitoring
What?
The Ryevitalise bat monitoring project is a landscape scale citizen science project, that uses passive detectors to record bat species and distribution within the landscape.
How?
The project uses passive acoustic detector equipment that is deployed by the public and volunteers. These frequency triggered detectors then record for up to four nights at a time before being collected. The recorded sound files are then uploaded to the BTO’s acoustic pipeline for analysis.
Why?
This project is gathering data on the types of bats (and some other animals such as small mammals and moths) and their distribution in the landscape. It is helping to guide potential conservation measures and decisions, that would help to increase roost sites and food sources, and improve habitat connectivity.

2) Ancient and Veteran tree recording
What?
The Ryevitalise ancient and veteran tree recording project is a citizen science project that is recording the locations, details, and assessing the health and condition of our oldest trees.
How?
Volunteers receive formal training on survey techniques and are then assigned a specific area to go and survey. These areas have been identified as potentially containing veteran and ancient trees and access has been agreed with the landowner or manager. Various measurements and observations are taken of the potential trees and this data is then uploaded to the Ancient Tree Inventory hosted by the Woodland Trust. Once uploaded, the records are verified.
Why?
Ancient and veteran trees are incredibly important for the ecology of woodlands, supporting everything from insects and fungi to birds and bats. For this project, our bats are of particular interest as ancient trees are critical for their summer roosts. By combining ancient tree surveying with bat monitoring, we aim to develop a deeper knowledge of the key bat populations and how they use our ancient trees.
The tree records data can guide conservation management requirements in these areas that will help to protect these trees and then also decisions on planting schemes that will be the veterans of the future.

3) Monitoring riverflies and water quality
What?
How?
Following the Riverfly Partnership Riverfly Monitoring method, a team of trained volunteers conduct a standardised kick sample and stone search at an assigned location at least once a month from May to October.
The volunteers will also take pH readings of the water, and test the levels of Nitrates, Nitrites, and Phosphates. All this data is then uploaded to the Anglers Riverfly Monitoring Initiative portal, where any breaches in a predetermined trigger level can be notified promptly to local bodies such as the EA to advise of potential problems.
Why?
Riverflies are freshwater invertebrates that spend all or part of their life living in a river, stream, or body of water. They are a key indicator species group, sensitive to pollution and changes in the river, and monitoring their presence, abundance and diversity on a regular basis is a useful way to assess the water quality of a river.

4) Juvenile fish population monitoring
What?
This volunteer project occurs annually in the Autumn, and seeks to record the species and abundance of freshwater fish populations within the River Rye catchment.
How?
After a formal training course, a small volunteer team led by a member of staff uses an Electro Fishing survey method to retain a representative sample of fish species present within the watercourse. Fish are attracted to the current, removed safely, and then various measurements are taken before being released back into the watercourse.
Why?
Fish are an ecological indicator of the quality of aquatic habitats. This monitoring programme is another method by which Ryevitalise can gain information and data about the health and status of the River Rye catchment. The data can point towards problems with habitat connectivity and the functional aquatic processes of the river, as well as the status of migratory fish species such as Atlantic salmon (Salmo salar) and sea trout (the anadromous form of brown trout, Salmo trutta).

5) Butterfly monitoring programme
What?
The Ryevitalise Butterfly monitoring programme is collecting data about the different butterfly species found on several transect sites within the Rye catchment.
How?
Led by a Ryevitalise team member, a trained group of volunteers carry out transects surveys. Transects follow a set route which is walked each week, recording any butterfly seen within 5m of the transect line.
Why?
We survey butterflies to gain a knowledge of the species in certain areas and habitats. This is useful as it can show certain population trends in species in specific areas. Surveying butterflies also allows us to understand the ecology of the site as well as the conservation value. The surveys will also give an insight to how successful current management work has been on some of the sites.
